Thanks I am familiar with the Big Tom IC, just looking for more details about make and fitment since we d owners have very little to go by considering nobody state-side has installed an aftermarket IC or even removed it for that matter and compared it against the 335i IC to see what if any differences there are.

I thought that if perhaps someone else did the work already that we could get more details. To bad he's not on the boards.

From what i seen, i took a better option with the wagner-tuning ic and my car is a 535d which has a bit different IC than the 335d. For you, it should be bolt on mod because it is made for the 335i (that has the same IC than the 335d and therefore use the same supports), is shorter than the Big Tom and expose more the water radiator to prevent water cooling issues and has a bit more capacity.

Big Tom IC: 450x300x102 - 13,50L
Wagner-tuning: 520x210x150 - 13,57L

From the link provided about his car, it has 410hp and 835nm with meth.

How do you know it is the same IC at the 335i? This is the question that we are trying to confirm.

While it looks to be the same IC as the 335i when looking at realoem, the cores could very well be differnt since the 335d not only has a different engine/turbo set-up but it runs at much higher boost pressures which may require a different core. There also seems to be at least 1 sublte physical difference when comparing the parts on realoem.

I wish we could track down this owner, he could help us out big time.

I'm not 100% sure about the 3 series, but in the 5 series the 535i and 535d share the same IC part number. Sometimes the pics in the realoem don't show the true design. The best is to compare the part numbers: same part numbers = same part. And this makes sense with the new cost savings policy from BMW, to share the same parts the most as possible for all production models.

Besides that, the wagner-tuning ic has a bar and plate core which is capable to handle with high pressure alot better than the stock tube and fin core.

I asked him but he didn't know what IC core he has, I think Vtech bought and installed everything for him. Does 335d have the same heat soak issue as the 335i?

Different part numbers, but they look the same. Connections might be different though.

We are still trying to either find an owner near a shop that is willing or vice versa that is familiar with the 335i IC so they can compare the differences.

I have an intercooler that I'm planing on installing when I get some time soon.

I'd like to get to the track before the install so I can see if there is any changes though.

the meth how many hp gives, without modification in Ecu map ?
i mean the only ADD horsepower by w-meth

If I could I would remove the DEF and other factors WE in the US of A have to have installed in our vehicles, when the REST of the world does NOT comply with US of A and EU. Dont even start with DIESELS truck which are not regulated, this is an issue most of us specially me is botheringsome

I for got to mention I hv been in close contact with Nick of Wagner ICs in USA and the Doc from Germany that actually went to Wagner in Germany and they had to do a 3D of the actual OEM IC to START making one for us, the 335i IC will NOT work with our "D" Hence, tubing is different , the DOC told me in 2 months they will have one for us, Nick told me 4 months. If you have seen the Wagner ICs they are SWEET looking and look almost OEM!!! I am waiting for that IC to come out.

Good info Axel, thanks. This info warrants another/new thread that can be updated periodically as more details become available (like the meth thread).

That is very strange. I have a close friend with a E91 335d (non LCI) and he followed my advice about the Wagner IC. It was a direct fit for his car.
Besides my mods, his car also has hybrid turbos. He wants to break the 420hp mark.

tiago this info I got was from the DOC in Germany, Wagner couldnt make a fix for the 335d since the 335i tubing would not match thats why they decided to scan it 3D and make one that is correctly and adpatable to our "D"s now remember although the same engine in Portugal its different tubing here in USA, maybe that is a factor but I doubt it cause the DOC is in Germany, dont know what to say on this
